folder2blog is a minimalist blog engine based on
plain text. You maintain a folder of text files,
one for each article, and folder2blog dynamically
maps it to blog-ish HTML/RSS2 output. Comments are
appended to each text file. Managing
articles/comments now becomes creating or editing
text files. For example, all you do is edit a
local folder of plain text files and sync it with
the server, manually or using tools such as rsync,
over SSH or FTP. The encoding may be anything
(UTF-8 by default). The HTML formatter is any
external program, such as markdown, that may act
as a pipe. The owner receives notification email
for each comment. There is basic spam protection.
